4 Claims.

The invention herein disclosed relates to a construction for pivotally securing a cover or door to a support such as a base or box. 'Ihe invention is particularly suitable, although not limited thereto, for securing the covers to cabi- I nets and boxes.

An object of this invention is to provide a hinge construction that is easily and readily installed and which facilitates the assembly of cabinets, boxes, etc., such as, for example, electrical meter and terminal boxes and switches. Another object of the invention is to provide a hinge construction with which the parts of the box and the hinge may be nished separately and assembled after being iinished. A further object of the invention is to provide such boxes and cabinets with a hinge construction that is comparatively inexpensive to manufacture.

Other objects and certain advantages of the invention will appear from the following detailed description of the embodiment of the invention disclosed in the accompanying drawing in which:

Fig. l is a plan view of a box constructed in accordance with the invention; the cover of the box is open and partly in section;

Fig. 2 is an elevation of one side of the box taken along the line 2-2 of Fig. 1;

Fig. 3 is an elevation of the same side of the box considered from the exterior of the box as 30 indicated by the line 3-3 of Fig. 1; and

Fig. 4 is a transverse, sectional elevation taken I along the line 4-4 of Fig. 2.

The box shown in the drawing is the usual sheet steel box having a bottom I and perpendicular sides or walls including end walls 2 and 3 and side walls 4 and 5. The cover 6 has perpendicular end and side flanges 'I and 8 and 9 and III respectively. These flanges embrace the upper edges of the side walls of the box in the closed position of the cover.

The cover 6 is pivotally secured to the side wall 5 of the box by a hinge II. The hinge consists of a heavy metal wire having end sections IIa and IIb shaped to form substantially semicircular loops. The plane of each of these loops is perpendicular to the axis of the wire. Intermediate the looped end sections II-a and IIb, there is a central section Il c shaped to form a substantially semicircular loop, the axis of which loop is perpendicular to the axis of the wire.

The wire and the looped central section IIe thereof extend along the inner surface of the side wall 5 and it is secured thereto against relative rotational movement by a machine screw I2 which passes through the looped section IIc 1936, Serial No. 81,818

and is threaded into an opening provided therefor in the side wall 5. A washer I3 is placed between the head of the screw and the looped section IIc of the wire. The looped end section I la of the wire passes through an opening 5a in 5 the side 5 and forms a loop perpendicular to the outer surface of the side 5, and the end thereof is received in an opening 5b in the side 5, the openings 5a, and 5b forming a pair of openings spaced unequally from the edge of the side 5 and receiving the ends of the looped section Ila. A similar pair of openings 5c and 5d, spaced longitudinally of the side 5 from the pair of openings 5a and 5b, receive the ends of the looped section IIb of the wire. The corresponding openings of these two pair of openings are equidistant from the edge of the side wall 5. In assembly, the looped sections IIa and IIb are passed through openings 9a and 9b provided therefor in the iiange 9 of the cover 6. 'Ihe cover 6 is thus pivotally secured to the side 5 of the box. The holes 9a, and 9b are located so that there is no binding between the holes and the looped sections II-a and IIb and the cover pivots about the edge of the flange 9.

From the above description of the specific embodiment illustrated, in the drawing itwill be seen that there is provided by this invention a cabinet or box and hinge construction such that the several parts may be finished separately and then assembled and that the hinge construction is comparatively inexpensive to manufacture.

It is apparent that various modifications may be made by those skilled in the art oi the details of the embodiment illustrated in the drawing and described in detail above within the principle and scope of the invention as expressed in the appended claims.

I claim:

1. A hinge construction comprising a heavy metal wire having end sections shaped to form substantially semicircular open loops, the plane of the loops being perpendicular to the axis of the wire, and a central section intermediate the end sections bent to form a substantially semicircular open loop having an axis perpendicular to the axis of the wire.

2. A hinge construction for a stationary and movable part which hinge construction comprises two aligned, coaxial heavy-wire loops, each loop having a substantially semicircular conguration and being adapted to pass through openings in the movable part and to have both ends thereof extending into the stationary part whereby a hinged connection is formed, and means adapted to secure the loops against movementl relative to the stationary part.

3. A hinge construction for a sheet metal box having a cover, which hinge construction cornprises two aligned, coaxial heavy-wire loops, each loop having a substantially semicircular configuration and being adapted to pass through openings in adjacent edges of the top and side wall of the box whereby a hinged connection is formed, and means adapted to engage the box and secure the loops against relative movement with respect to the box.

4. A hinge construction for a sheet metal .box
